Arsenal defender Bacary Sagna has called on the squad to become wiser in converting possession into wins.
The Gunners are in the midst of a pre-Christmas slump - losing at Olympiakos in the Champions League and at home to Swansea in the preceding Premier League clash.
Without a win in four, Arsene Wenger finds himself under renewed pressure at the head of affairs - but France star Sagna maintains that the players need to help out by becoming more ruthless.
"We just need to be wiser. We have had the opportunity to win games, and for some reason we don't," Sagna told Arsenal Player.
"We need to work on it. We need to stay focused on the pitch and we need to work harder during training sessions. If we do that everything will be fine. I don't worry about it.
"Everyone is good in the Premier League. Everyone can beat everyone. The top teams are the most consistent ones.
"They just go game by game and want to take points. We have to step up and show the opposition who is on top. We've made some mistakes in the past and now we want to impose ourselves on our season."
Arsenal travel to The Hawthorns to face this season's surprise package West Brom on Saturday, and will start the game five points and five places below their hosts.
Parker, 25, has been with Kevin Blackwell's Shakers squad for a number of weeks on a trial basis before agreeing his deal.
The player made 52 appearances for Leeds but struggled with injuries before being released over the summer.
Parker also enjoyed loan spells with Bradford, where he made his senior bow, as well as Darlington and Carlisle.
The decision was announced following a meeting of UEFA's executive committee in Lausanne on Thursday.
UEFA general secretary Gianni Infantino told a press conference after the meeting: "Some important decisions have been taken.
"UEFA Euro 2020 will be staged across the continent, in various major cities, following a decision taken today. A Euro for Europe follows an initial idea by UEFA president Michel Platini.
"The response has been extremely positive from all the national associations."
The format and number of host cities that will be involved in the tournament, which will feature 24 teams, will be decided by UEFA's national teams committee with the bidding process to begin in March.
A final announcement is expected in the spring of 2014 with the Football Association having already put Wembley forward as a possible venue for the final.
Turkey had initially bid to host Euro 2020 and the nation's representative, Senes Erzik, opposed the decision.
UEFA also announced that the 2013/14 European women's under-17 tournament will be hosted in England.
Wilkinson arrived at Victoria Road after his release by Portsmouth in 2010 and spent his first two seasons on loan at non-league sides Boreham Wood and Dartford.
But he has been a regular part of manager John Still's side this term and even bagged four goals in the process.
Still said: "When Luke Wilkinson signed as a young player from Portsmouth we knew it would take him a little bit of time to settle in.
"He's come in this year and done fantastic and made his place in the team his own.
"He looks to be another young and exciting player that we seem to develop here and I am delighted he has signed another contract."
